DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

According to an embodiment of the present invention, there is provided a cover assembly 2 which forms a pressurized chamber for swimming training as shown in FIG. 1. The swimming pool cover assembly 2 includes an inflatable frame 4 formed from an interconnected three-dimensional (3D) lattice of inflatable tubes. The cover assembly 2 further includes a cover 6 supported by the frame 4 to cover a swimming pool (not shown). The cover 6 partitions off the pool from its surrounds so that the chamber can be pressurized to simulate altitude training. Advantageously, the cover assembly 2 can be conveniently set up at a local pool to enable athletes to altitude train without needing to go to the trouble and expense of traveling to the mountains.

The entire frame 4 can be inflated at a single inflation point as the inflatable tubes are in fluid communication with each other. As can best be seen in FIG. 1c , the frame 4 includes three wall frame portions 8 a, 8 b, 8 c. Each adjacent pair of wall frame portions 8 are aligned along the sides of a respective swimming lane. As can best be seen in FIG. 1b , the frame 2 also includes an inflatable roof portion 10 forming a rectangular multi-dimensional array.

The cover 6 includes multiple panels of sheet material for releasably affixing with a hook-and-loop (e.g. Velcro™) fastening arrangement 6 a to the top and sides of the frame 4. In particular, the cover 6 includes a roof sheet 12 for covering the roof portion 10 and removable side panels 14 for affixing within endless rectangular portions of the external and internal (i.e. partitioning) wall frame portions 8. The sheet material is air impervious and formed from transparent polymeric or plastic material.

The cover assembly 2 further includes four strip doors 26 at its ends 2 a and in register with the swimming lanes. Each strip door 26 includes a number of hanging PVC strips 28. In addition, some of the side panels 14 can have entry/exit slits 30 which can be releasably closed with a hook-and-loop (e.g. Velcro™) fastening arrangement.

The frame 4 includes handles 32 to facilitate handling when the frame 4 is deflated. The handles are located at the corners of each endless rectangular portion of the wall frame portions 8 a, 8 c that are external. The frame 4 includes fastening rings 34 through which backstroke flags can be transversely fed and fastened across the inside of the cover assembly 2. The inflatable frame 4 is formed by stitching, gluing or thermal welding polyvinyl chloride polyvinyl chloride (PVC) material together. In practice, a blower can be continually required to inflate the inflatable frame 4 as air leaks from the frame 4.

The cover assembly 2 further includes conduits 50 suspended in the pressure chamber from the top of respective wall frame portions 8. The conduits convey air into and out of the chamber of the cover assembly 2 to adjust the air conditions within the internal chamber as required to simulate altitude (e.g. up to 3.5 km above sea level). The cover assembly 2 further includes a pump 52 for pumping air in or out of the internal chamber via the conduits 50. Typically, the pump 52 is a blower and blows air of reduced oxygen content (compared with the surrounding atmosphere) into the chamber. However, the internal air pressure of the chamber is only slightly greater than the external atmospheric pressure. In this manner, the blower takes in air from the surrounding atmosphere, and adjusts the oxygen content in the air, before providing the air into the chamber.

The cover assembly 2 as long enough to completely cover a 25 metre or 50 metre swimming pool. The separation between each adjacent pair of wall frame portions 8 accommodates a swimming lane.

FIG. 2 shows a bed cover assembly 200 in which a king sized bed or exercise bike can be located. The bed cover assembly 200 includes an inflatable frame 202. The frame 202 is rectangular and a leg portion 204 of the frame includes a valve 206 through which air can be pumped during inflation. An oversized sheet cover 208 is sealingly fastened along each inflatable straight portion of the frame 202, and rests on the ground adjacent the frame 202 to facilitate sealing of the internal pressure chamber. Advantageously, the pressure chamber does not have an internal floor which could otherwise be breached by a leg of the bed.

The cover 208 is fitted with a one-way valve 210 (i.e. pressure adjustment means) for facilitating adjustment of the pressure in the pressure chamber with a connected pump. The cover 208 also includes a pair of re-sealable zip or loop-and-hook entrances 212 a, 212 b to gain access to the chamber.

FIG. 3 shows a seat (e.g. lounge chair or couch) cover assembly 300. The assembly includes an inflatable frame 302 having a square base portion and two crisscrossed arch portions. Anchor lugs 304 are located at each corner of the base portion, and handles 306 extend from the frame 302 to facilitate handling.

The cover assembly 300 includes a transparent sheet cover 308 sealingly fastened along each inflatable portion of the frame 202. In addition, a transparent sheet floor 309 is sealingly fastened along each straight inflatable portion of the base of the frame 202. The cover 308 also includes a pair of re-sealable zip or loop-and-hook entrances 310 a, 310 b to gain access to the sealed internal chamber. A valve is provided in the cover 308 to facilitate pressurizing the chamber with an external vacuum pump.

Advantageously, the embodiments of FIGS. 2 and 3 enable athletes to undergo altitude conditioning when relaxing at home in bed or on a seat, or using an exercise bike.

FIG. 4 shows an inflatable dome cover assembly 400 including dome lattice framework 402 which can be provided over the swimming pool cover assembly 2. The framework 402 includes a number of arched and straight inflatable portions which are in fluid communication with each other. Individual roof panels 404 can be fitted within each cell of the lattice framework 402. Alternatively, a flaccid sheet cover can cover the framework 402. The dome cover assembly 400 further includes a built-in pump storage container 406 for containing the pump 52. In turn, the pump fills the inflatable portions of the framework 402 and swimming pool cover assembly 2, and adjusts the oxygen content and pressure inside the chambers within the swimming pool cover assembly 2.

A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.

In the preferred embodiment, the pump adjusted the pressure and oxygen content of the air in the chamber. In a further embodiment, the pump may also adjust the humidity, temperature or other like air conditions.

In one embodiment, the inflatable tubes (i.e. portions) of the frame 4 may be partitioned into isolated sections which are separately inflatable so that a puncture or leak in one section will not result in deflation of the other sections.

In one embodiment, the cover 6 can consist of a single sheet of material.

In one embodiment, the cover assembly 2 can be located over a running track to cover running lanes. The cover assembly 2 may be a 45 m×1.6 m×2.2 m long unit designed for hypoxic sprint training. In one embodiment, the present invention can be utilized in an animal exercise training area for training animals such as horses.

In one embodiment, the cover assembly 2 includes at least one internal partition to form more than one internal pressure chamber in register with respective lanes, with each chamber able to be kept at a different pressure.
